SLlVER-BREAKER FOR S PINNING=MACHINES.

EJPECIPICATIQN forming part ofLetters Patent No. 355,452, c'latedJ'anuary 4, 1887.

Application filed September-E1, 1386. Serial No. 215,554. (No model.)

To aZZ whom, it may concern.-

Be it known that we, HENRY E. KAY and GHARLEs F. HILL, citizens of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Sliver-Breakers for Spinning-Machines; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in devices employed in cotton-spinning machinery to break the roving or sliver in advance of the drawing-rolls. In devices heretofore employed for this purpose one or more eyes or loops have been provided, through which the sliver is required to be threaded. In our improvement all additional threading of the sliver is dispensed with and the construction sim plified.

The drawings accompanying this specification represent,in Figure l,a vertical section of so much of the spinning machinery, with our invention attached, as is necessary to illustrate the working of the latter. Fig. 2 is a partial end elevation. Fig. 3 is a view of our invention detached, showing its bearing and its position relative to the sliver.

The same letters of reference indicate iden tical parts in all the figures.

In the drawings, A represents a section of aseries of drawing-rolls of a spinning-frame.

.B'is the trumpet which guides the roving or sliver to the drawing-rolls, and which is supported in any usual or well-known manner in the proper position to accomplish this. In our construction we attach this trumpet to the top of a plate, 0, which is provided with apertures through which it is bolted or secured in position. The lower end of this plate is pro vided with a sleeve, D, which serves as a bearing in which is-journaled the rod or shaft d. This. rod or shaft is provided at the end extending beyond the plate 0 with a hooked arm, (1, and at its opposite end with the arm (2 bent as shown in the drawings. The hooked portion of the arm (1 extends slightly above the trumpet and is made with a blunt or roughened inner edge. The arm d at the opposite end of the rod or shaft, has a bend, e, midway of said arm, and so located in respect to the arm that when said arm is turnedup over that portion of the sliver extending between the drawing-rolls and a guide or guide-eye conducting the sliver to the spinning devices the inner side of this bend will rest upon the sliver. The end of the arm d is made smooth,and may be, when desired, provided with a ball, 6, adjusted to furnish the requisite amount of weight to insure the proper action of the device.

While we have shown the rod or shaft d mounted in'sleeve D, attached to the plate 0, this construction may be considerably varied. The trumpet may be attached to the frame independent 'of the plate 0, and in place of saiding to the willof the maker, as one form may,

be found more effective than another.

The operation of the device is as follows:

Before the roving or sliver is passed through the drawing-rolls to the spinning mechanism our device occupies the position shown in dotted lines in Figs. 1 and 2. Assoou as the roving or sliver has been properly placed the shaft (Z is turnedby the arm (1 until the arm at rests upon the sliver beyond the drawing-rolls, as shown in Figs. 1 and 3, in which position the arm (1 stands as shown in full lines in Figs. 2 and 3. The weight of arm d is such that it is supported by the sliver as long as the same is unbroken and the proper size and strength. \Vhen, however, it becomes injuriously weakened or broken, the arm d drops and the arm at is brought sharply against the roving close to the open mouth of the trumpet, and breaks the same at that point. As soon as the sliver is broken the shaft (2 and arms d and d turn to the position shown in dotted lines in Figs.

1 and 2, and are entirely out of the wayin the next introduction of the sliver.

It may sometimes be found advantageous to 'have the arm (I located between the trumpet and the drawing-rolls.

What we claim, and desireto secure by Letters Patent, is

1. The combination, with the drawing-rolls 1 ind guides for the roving, of a shaft journaled 3. The combination, with the'plate C, hav- )e1ow and transversely to said drawing-rolls ing sleeve D, of a shaft, d, provided with arms llld. provided with an arm at each end, said d and d substantially as described.

LIIDS being of greater length than the distance In testimony whereof We affix oursignatures r 5 )f the shaft from the path of the roving, subin presence of two witnesses.

.tantially as described. 7 2. The combination, with the drawing-rolls 1 ind guides for a roving or sliver, of a shaft J ournaled below said drawingrolls, trans- Vitnesses: v rersely thereto, provided with arms d and d, GEORGE E. BAMFORD, mbstantially as described. CLARENCE E. BURY.
